No. I can't add a column to the table or change the table in any way. I
can insert into and select from the table.

using elements of one ruby array as indices to another
Still struggling with my first ruby program. In the following code, I am
trying to get the index from each time a certain letter, 'guess', appears
in array 'secret_word' and then using those indices to insert the same
letter into another array, 'user_word', without disturbing any of the
other letters that might already be in user_word. I decided to store the
indices selected from 'secret_word' in an array, 'indices'. The error
message implies that each element of indices is an array, not a fixnum as
expected. Bottom line, it will not let me use the element from indices to
index into user_word. Help?
if secret_word.include?(guess) #secret_word is an array of chars. guess is
a char.
indices = Array.new
indices<< secret_word.each_index.select{ |letter| secret_word[letter] ==
guess } #verified that this array fills correctly

have so far been able to highlight my query within my returned results.
However, I want to highlight this same query when visiting the next page

Whenever I try and include a statement like this, I get an error, which
I'm thinking is because I'm not trying to access the query properly.

crop an image responsively keeping the center of the image visible (horizonally)
crop an image responsively keeping the center of the image visible
(horizonally)
Here is the website I need help with: www.aaronrhoades.com/blog The header
image grows when it's on a bigger browser (e.g. on a TV screen) and
shrinks when it's on a smaller browser. BUT, it stops shrinking at a
certain point because I don't want it to get too small.
The problem: once the image stops shrinking then it stays glued in one
spot horizontally based on the left side of the image. I want it to move
left so that the logo stays visible. Something like a "margin-left:-50%;"
would work for mobile, but obviously that messes it up on a full screen.
CSS only would be great if possible, otherwise I am ok with jquery. PHP
might be good since this is a wordpress, I'm just not too familiar with
it. Here is my code:
#nicelogo img{
width: 100%;
min-width: 683px;
min-height: 250px;
text-align:center;
margin-left:auto;
margin-right:auto;

SVN+SSH On Ubuntu: Locking down security - Passwords
SVN+SSH On Ubuntu: Locking down security - Passwords
Good day,
I have setup a server running Ubuntu 12.04 LTS. I have left the default
SSH port as-is for now, and have set up a DynDNS.org account.
From a machine, running linux, on a separate network, I am able to query
my server via SVN+SSH:
svn --username myName ls
svn+ssh://myName@superdude.dyndns.org/usr/local/svn/repos/private
So far so good: I am queried for the user's password, and an SSH
private/public key pair appears to be generated. However, I am concerned.
I thought the point of private/public keys was that I'd have to provide
the client with the appropriate key in advance. I want to lock down this
server so that the people connecting to my SVN server have both a keyfile
I gave them in advance, and the password for user "myName". Is there
something I'm missing? At this point, all someone appears to need is the
URL to my SVN server, and the password for user "myName", and they are in.
How can I lock this down tighter?
Thank you!

javascript/DOM event name convention
javascript/DOM event name convention
Hi when I started doing web development, I realized javascript event names
were all in lower case with no separators, i.e. "mousedown", "mouseup",
etc. And when working with the jQuery UI library, I noticed they also use
the same convention; i.e. "dropdeactivate" as in the following example
javascript $( ".selector" ).on( "dropdeactivate", function( event, ui ) {} )
While this works well for names that are only 2 or 3 words, it is really
awful for names with more words on it.
Despite of this I followed that convention too when I have to fire custom
(synthetic) events that I created, until recently when I decided it was
better to start using some form of separator. Now I use something like
"drop:deactivate", or "app:ready".
on iOS apple recently added this event for the HTML 5 Airplay API, and I
agree with the autor of this post
http://www.mobilexweb.com/blog/safari-ios7-html5-problems-apis-review when
he says:
I think "webkitcurrentplaybacktargetiswirelesschanged" has won the record:
the longest JavaScript event name ever.
What is the reason behind this weird convention? why not use any form of
separator or camelCase convention to name the events in a more readable
way?
I think there is a reason for that, lot of clever people worked on this...
But after a while I'm still wondering why?

Project Euler 22, off by 18,609
Project Euler 22, off by 18,609
I'm working on problem 22 of Project Euler:
Using names.txt (right click and 'Save Link/Target As...'), a 46K text
file containing over five-thousand first names, begin by sorting it into
alphabetical order. Then working out the alphabetical value for each name,
multiply this value by its alphabetical position in the list to obtain a
name score.
For example, when the list is sorted into alphabetical order, COLIN, which
is worth 3 + 15 + 12 + 9 + 14 = 53, is the 938th name in the list. So,
COLIN would obtain a score of 938 × 53 = 49714.
What is the total of all the name scores in the file?
My code (below) getst the answer 871179673. The correct answer should be
87119828, which makes me off by about 18k.

score = 0
for letter in name:
if letter == "A": score += 1
elif letter == "B": score += 2

Can't change permissions for header.php
Can't change permissions for header.php
Here is my official WordPress forum support plea:
http://wordpress.org/support/topic/headerphp-is-not-updating?replies=4
I changed all the permissions via FTP, currently set to 777. Originally
666, but that didn't work, so here we are.
I cleared all of my browser caches.
I added:
define('DISABLE_CACHE', true);
to wp-config.php
I don't know what else to do at this point. The file on my server reflects
the changes I made, but if you look at the source on the website, via
Firebug or whatever, it isn't there.
From the native WordPress editor, it says I can't edit the file because
the permissions aren't set. What's really absurd is that this is a custom
theme specifically for this website. Whose business is it if I want to
change it?
Can anyone please at least verify that the correct 'header.php' is in
wp-content/themes/themeofchoice?
I greatly appreciate any assistance.

I have to 'parse' a format string in order to extract the variables.
E.g.

External CSS - How do I write/apply tags in HTML page (beginner)
External CSS - How do I write/apply tags in HTML page (beginner)
My External CSS and template was created by a friend fluent in CSS. But my
friend isn't understanding that I don't know HOW to 'apply' (write) the
tags in the HTML page to 'call' the CSS.
I know the difference between id (#whatever) and class (.whatever) But I
don't know if a CSS entry like
.header caption (with styles listed) translates then to 'p class="header
caption" with opening/closing tags ???
What I'm looking for, but not finding on the web, is a listing of how the
most common tags are written as css. For example, I know
p class="left" applies the CSS to align left, instead of HTML tag
align="left" But How do I write the actual tag for .table .td .tr
Is there a website to show: "This is the tag in HTML, no External CSS"
"This is the way to write the same tag for External CSS"
Second question... Other than for the 'p class' or easy tags, do I start
every tag with: class="" ? p class="" ? div class="" ?
When do I use SPAN vs DIV ?
I have searched for how to apply External CSS, for what tags to use--yes,
I understand that every person might use different naming for divs and
classes-- but I really need examples that will show the basic tags so I
can plug in the 'different naming' from my
'external css'
Is there one website that shows (all on one page) examples of the tags? A
website tutorial that doesn't assume novices already know how to write the
tags to apply css?
Thanks Lifes

Rumors of performance PHP
Rumors of performance PHP
Once, I heard in a lecture that use ?> to close PHP files were causing the
performance fall, is this true?
It's funny that many php applications, and frameworks really do not close
the files with ?>. Could be due boilerplate or performance?
The spaces in the code, influences the application performance?

How can I get a view by id from a layout in Android?
How can I get a view by id from a layout in Android?
This is the only way I can find but it seems hacky:
public View getViewByIdFromLayout(int id) {
for (int i = 0; i < layout.getChildCount(); i++) {
View v = layout.getChildAt(i);
if (v.getId() == id)
return v;
}
return null;
}
Is there a better way to do this? These views were created
programmatically, not via xml, and the views' ids will be unique in a
given layout but may be reused in other layouts.

Using devenv.exe from the command line and specifying the platform
Using devenv.exe from the command line and specifying the platform
I'm attempting to compile a visual studio solution using devenv.exe from
the command line. I can get it to work but all the projects in the
solution are compiled for AnyCPU and I want them to be compiled for x86.
Both the debug and release configurations are set to x86 for all projects.
When I compile from within the IDE it works fine. But when I try to build
the solution from the command line it always builds all projects for
AnyCPU. Is there a way to devenv.exe to build in x86 only?

PhoneGap - exec() call to unknown plugin
PhoneGap - exec() call to unknown plugin
I've been trying to use Phonegap Image Resizer plugin in my project, but I
couldn't make it work.
The error log returns: D/PluginManager(13992): exec() call to unknown
plugin: com.webXells.imageResizer
I've moved all the necessary things into my project folder. Here's the
structure:
/assets
/js
cordova.js
imageresize.js
/www
index.html
upload.html
/src
/com
/webXells
/ImageResizer
ImageResizerPlugin.java
I've also include the plugin into config.xml in /res/xml:
<feature name="imageResizer">
<param name="android-package"
value="com.webXells.imageResizer.ImageResizePlugin"/>
</feature>
In upload.html I've included the plugin like so:
<script type="text/javascript" charset="utf-8"
src="../js/imageresize.js"></script>
And this is how I call a method to use it:
function onPhotoDataSuccess(imageData) {
window.imageResizer.resizeImage(
function(data) {
var smallImage = document.getElementById('smallImage');
smallImage.style.display = 'block';
image.src = "data:image/jpeg;base64," + imageData;
//image.src = imageData;
},
function (error) {
console.log("Error : \r\n" + error);
},
imageData,
0.5,
0.5,
{
imageDataType:ImageResizer.IMAGE_DATA_TYPE_BASE64,
resizeType:ImageResizer.RESIZE_TYPE_FACTOR,
format:'jpg'
}
);
}
So, inside the imageresize.js the method that I wanna use looks like this.
You can refer to the above link if necessary:
ImageResizer.prototype.resizeImage = function(success, fail, imageData,
width,
height, options) {
if (!options) {
options = {}
}
var params = {
data : imageData,
width : width,
height : height,
format : options.format,
imageDataType : options.imageType,
resizeType : options.resizeType,
quality : options.quality ? options.quality : 70
};
return
cordova.exec(success,fail,"com.webXells.imageResizer","resizeImage",[params]);
}
In the above code, I noticed that com.webXells.imageResizer didn't called
as reported in the logcat. What confuses me is the fact that I have
included it in config.xml and moved the java file in src folder. Why can't
it be called even though I have done all the stuff that is necessary?
Some researches I made, says to declare the plugin in plugin.xml, but I
don't have the file inside res/xml. So, I put it in config.xml instead.
Other recommend to use <gap:plugin name="com.phonegap.plugins.example" />
but Eclipse found error to this.
So, how do I get around this? Have I called the method in HTML correctly?
Or there is something I missed?

Content not appearing on scroll in Safari
Content not appearing on scroll in Safari
I made a site for a client recently and I've been told that they are
seeing a bug that is safari specific. The site content fills up the
browser window, but when they scroll down, the rest of the site will not
load all the way. They fix this by resizing the browser window, in which
case the rest of the content begins to appear.
I've tried to recreate this bug to no avail. Maybe you can? Or maybe you
know what the issue is? I was thinking maybe an overflow problem?
the site is http://theherbalosophy.com
you can see a screenshot of the bug at

Perfect forwarding and ambiguity of function-parameter binding
Perfect forwarding and ambiguity of function-parameter binding
I am experimenting with the perfect forwarding feature of C++11. Gnu g++
compiler reports an ambiguity issue of function-parameter binding (the
error is shown after the source code below). My question is why is it so,
as following the function-parameter binding process I don't see the
ambiguity. My reasoning is as follows: call to tf(a) in main() binds to
tf(int&) since a is an lvalue. Then function tf forwards the lvalue
reference int& a to function g hence the function void g(int &a) should be
uniquely invoked. Thus I do not see the reason for ambiguity. The error
disappears when the overloaded function g(int a) is removed from the code.
This is strange as g(int a) cannot be a candidate for binding with int &a.
Here is my code:
void g(int &&a)
{
a+=30;
}
void g(int &a)
{
a+=10;
}
void g(int a) //existence of this function originates the ambiguity issue
{
a+=20;
}
template<typename T>
void tf(T&& a)
{
g(forward<T>(a));;
}
int main()
{
int a=5;
tf(a);
cout<<a<<endl;
}
Compilation g++ -std=c++11 perfectForwarding.cpp reports the following
errors:

XLConnect is loaded automatically when I start R session
XLConnect is loaded automatically when I start R session
I got a problem with the R package "XLConnect".
Every time I open R, this package is automatically loaded.
So I thought it had been included in the default packages for some strange
reason, and I wrote like this:
getOption('defaultPackages') [1] "datasets" "utils" "grDevices" "graphics"
"stats" "methods"
It does not appear in the default packages; now I really don't know what
to do.
I ask for a help.
Thanks in advance.

1) We are using 3rd party program that can deploy programs and launch
powershell script as well.
The problem is though that program launch script as Administrator user so
powershell script is not allowed to search for files on
C:\Users[some_other_user] folder.
Is there a way to force search on restricted folders as well?
2) Second question is not so important but is it possible somehow to
include in $filePath not only C: but D: as well?
I'm making a script which would search for a file. If file is found it
will write txt file on server with computer's name and path where file is
located.
$filePath = "c:"
$fileName = "somefile"
$Computer = Get-Content env:computername
$srvpath = "\\server\share$\FindFileScript\$Computer.txt"

Is it possible to add sub-items to a YML list?
Is it possible to add sub-items to a YML list?
Given the following YML format, is it possible, or advisable to map URLs
so that components like nav lists can be both populated and linked?
It can be populated:
products:
- Wizzy Widgets
- Doohickeys
- Thingamabobbers
renders via the following ERB (where the file is /data/product_types.yml):
<% data.product_types.products.each do |product_type| %>
<li><a href="#"><%= product_type %></a></li>
<% end %>
to output the following markup
<li><a href="#">Wizzy Widgets</a></li>
<li><a href="#">Doohickeys</a></li>
<li><a href="#">Thingamabobbers</a></li>
but can it be linked also
products:
- Wizzy Widgets:
- url: "/wizzy-widgets"
- Doohickeys:
- url: "/doohickeys"
- Thingamabobbers
- url: "/thingamabobbers"
through ERB like so:
<% data.product_types.products.each do |product_type, product_url| %>
<li><a href="<%= product_url %>"><%= product_type %></a></li>
<% end %>
so that it outputs the following markup?
<li><a href="/wizzy-widgets">Wizzy Widgets</a></li>
<li><a href="/doohickeys">Doohickeys</a></li>
<li><a href="/thingamabobbers">Thingamabobbers</a></li>
I know this particular example doesn't work. I'm just trying to give an
example of what I'm looking to do. Is this a bad practice? If so, how
would you approach it?

findViewById in android doesn't return child layout
findViewById in android doesn't return child layout
I inflate a view. Using the newly created layout, I find a child to set a
property. But the child I get (mealName here) is not the good one. Having
my mealList containing multiple mealName, it's always the first one that
is returned.
RelativeLayout mealNameLayout = (RelativeLayout)
inflater.inflate(R.layout.planner_list_item_meal_title, mealList);
TextView mealName = (TextView) mealNameLayout.findViewById(R.id.mealName);
//Set meal name.
mealName.setText(meal.name);
By making this modification (not attaching automatically the relative
layout to the list):
RelativeLayout mealNameLayout = (RelativeLayout)
inflater.inflate(R.layout.planner_list_item_meal_title, mealList, false);
I'm having better results, but still very weird behavior. Looks like using
findViewById when having multiple items with the same id is not a good
idea. Even though there is only one item having this id in the children.
Any idea on what's going on?

Got time complexity questions here:
for i = 1 to n
if something
p = p*c
c = c*c
For line 1, the time complexity should be n, but what about line 3 and 4?
is that n^2? or n^n?

Application works with app.all but not with app.use... not sure why
I'm having some problems trying to implement some middleware in my app.
Specicially, the app.use() does not seem to catch and I don't understand why.
Below is roughly what I have.
routes/index.js
var Sessions = require('../events');
module.exports = exports = function(app) {
app.use(Sessions.isLoggedIn);
//app.use() does not catch but this does
//app.all('*', Sessions.isLoggedIn);
// Home Page
app.get('/', displayHome);
app.get('/:library/:books', displayLibrary);
}
events.js
module.exports = exports = {
isLoggedIn: function(req, res, next) {
console.log('isLoggedIn');
return next();
}
Any suggestions as to why app.use() is not catching?

problems implementing secured images on google app engine blob store?
problems implementing secured images on google app engine blob store?
Our project requires the images to be secure. The solution right now is,
to implement an authorization header. The front end makes an http call to
the image url with authorization credentials. once the image is
downloaded, an image tag is created and the url is assigned as a src.
Since the url was just called, its being served from the cache the second
time, and it works.. mostly.. we have some issues, where safari handles
cache differently.. also in chrome it fails when the web console is open.
We would like to have a more reliable method. Appreciate any input.

Javascript library combinations
Javascript library combinations
Question, lately I have been wandering around with Backbone.js, and
underscore/require and other libraries, what other combinations are out
there for Backbone? or Angular.js? I mean what are other stable and
reliable combinations to make with JS libraries?
All your answers are appreciated.

store.load() triggers read + create
store.load() triggers read + create
I'm developing a app where a list is automatically refreshed every 15 sec.
To do so, I load the store every 15 sec from server (sending the params)
via php page linked to a postgreSQL DB. So far, so good, and it works OK.
Buy I have noticed that every time the store is loaded, it sends two
requests to the server (read + create). While the read request is
necessary to load new elements to the store, the create is completely
useless, because it sends the whole store as payload and receives nothing
making use of the network for nothing. How can I make the store to read,
and only read, from the server when it loads?
Thanks

Most pythonic way to convert a string to a octal number
Most pythonic way to convert a string to a octal number
I am looking to change permissions on a file with the file mask stored in
a configuration file. Since os.chmod() requires an octal number, I need to
convert a string to an octal number. For example:
'000' ==> 0000 (or 0o000 for you python 3 folks)
'644' ==> 0644 (or 0o644)
'777' ==> 0777 (or 0o777)
After an obvious first attempt of creating every octal number from 0000 to
0777 and putting it in a dictionary lining it up with the string version,
I came up with the following:
def new_oct(octal_string):
if re.match('^[0-7]+$', octal_string) is None:
raise SyntaxError(octal_string)
power = 0
base_ten_sum = 0
for digit_string in octal_string[::-1]:
base_ten_digit_value = int(digit_string) * (8 ** power)
base_ten_sum += base_ten_digit_value
power += 1
return oct(base_ten_sum)
Is there a simpler way to do this?

Calculate a trig function with an input and output in degrees
Calculate a trig function with an input and output in degrees
I'm trying to make a calculator for some calc homework, but the
information is given in degrees and the answer must be in degrees. I tried
using the Math.toDegrees and Math.toRadians but the answer isn't correct.
public static double crossProduct() {
Scanner in = new Scanner(System.in);
System.out.println("enter angle in degrees");
double angle = in.nextDouble();
System.out.println("x1 = ");
double x1 = in.nextDouble();
System.out.println("y1 = ");
double y1 = in.nextDouble();
System.out.println("z1 = ");
double z1 = in.nextDouble();
System.out.println("");
System.out.println("x2 = ");
double x2 = in.nextDouble();
System.out.println("y2 = ");
double y2 = in.nextDouble();
System.out.println("z2 = ");
double z2 = in.nextDouble();
double mag1 = Math.sqrt((x1 * x1) + (y1 * y1) + (z1 * z1));
double mag2 = Math.sqrt((x2 * x2) + (y2 * y2) + (z2 * z2));
double res = mag1 * mag2 *
Math.toDegrees(Math.sin(Math.toRadians(angle)));
System.out.println("cross product = " + res);
return res;
}
inputting <0,2,0> and <0,5,0> and angle = 90 degrees should give the
answer as 10. instead it returns:
572.9577951308232
Any ideas?
EDIT: Also, if anyone has a better/shorter way for inputting the
components, that would be amazing.

double mag1 = Math.sqrt((x1 * x1) + (y1 * y1) + (z1 * z1));
double mag2 = Math.sqrt((x2 * x2) + (y2 * y2) + (z2 * z2));
double res = mag1 * mag2 *
Math.toDegrees(Math.sin(Math.toRadians(angle)));
System.out.println("cross product = " + res);
return res;
}
inputting <0,2,0> and <0,5,0> and angle = 90 degrees should give the
answer as 10. instead it returns:
572.9577951308232
Any ideas?
EDIT: Also, if anyone has a better/shorter way for inputting the
components, that would be amazing.

Different types of Users with simplemembership in ASP.NET EF code first
Different types of Users with simplemembership in ASP.NET EF code first
In my app I want to have two different types of users. This types differ
not only in role but also in attributes. I am using simpleMembership for
userManagement and I want to ask what's the best way or practise to create
data model for my situation in EF using code first. I was thinking about
creating two another tables UsersType1 and UsersType2 which will have one
to one relationship with table userProfiles so in the model I would have:
public class UserType1{
attr1
attr2
....
public int userProfileID {get; set;}
public virtual UserProfile userProfile {get; set;}
}
And same way for table UserType2.
I want to ask if this is a good way to go and if so, how should I modify
userProfiles table to be able to access UserType1 and UserType2 through
userprofile in code.
Thank you.

XSI: namespaces removing
XSI: namespaces removing
As part of my requirement, I need to route a response coming from my
dp:url-open in Datapower tool, serialize it and then send it to another
link.
Issue is that response is holding so many namespaces in its every element.
I know its the kind of format generated automatically, but i need to
remove them completely.
I went through few posts in internet and used exclude-result-prefixes at
start of my XSLT and i am able to get rid of most of namespaces like dp
and dpconfig related to Datapower, but xsi: and xmlns: are still appearing
in my string. How to get rid of that one also?
Please note that i cant use another XSLT as suggested in few posts. Is
there any other way, please suggest.
Below is my xml serialized.

Python can't keep up with time
Can anybody explain the following?
timex = [2012, 3, 1]
epoch = calendar.timegm(datetime.datetime(*timex).utctimetuple())
date = datetime.date.fromtimestamp(epoch)
print date # [2012, 2, 29]

epoch = calendar.timegm(datetime.datetime(*timex).utctimetuple())
date = datetime.date.fromtimestamp(epoch)
print date # [2012, 3, 14]
I'm not sure if it has to do with my misunderstanding of tuples, lists or
time in general, but python is always a day behind :P

Linux Threads and process - CPU affinity
Linux Threads and process - CPU affinity
I have few queries related to threads and Process scheduling.
When my process goes into sleep and wakes back, is it always that it will
be scheduled on the same CPU that it got scheduled before?
When i create a thread from the process, Will it also be executed on the
same CPU always? Even if other CPU's are free and sleeping.
I would like to know the mechanism in Linux in specific. Also i am
creating the threads through pthread library. I am facing a random hangup
issue which is always not reproducible. Need this information to proceed
in the right direction.

Why this opcode doesn't work properly on ARM
Why this opcode doesn't work properly on ARM
Writing the opcodes on ARM, I face an error.
8054: e92d1fff push {r0, r1, r2, r3, r4, r5, r6, r7, r8, r9, sl, fp, ip}
The above is the result of disassembly by objdump; \xe9\x2d\x1f\xff is the
same to push {r0-r12}.
But in another program, this opcode doesn't work properly like:
1e75: e9 .byte 0xe9
1e76: 1f2d .short 0x1f2d
1e78: Address 0x06001e78 is out of bounds.
Any ideas?

// Create calendar with no events
$("#calendar").fullCalendar({ events: [] });
// Add event to calendar
$("#calendar").fullCalendar('renderEvent', e);
// Remove event from the calendar
$("#calendar").fullCalendar('removeEvents', 1);
// Re-add event
$("#calendar").fullCalendar('renderEvent', e);
While this doesn't (http://jsfiddle.net/BNmrQ/2/):
// A simple event object
e = {id: 1, title: 'a', start: Date.now()/1000 };
// Create calendar with the event
$("#calendar").fullCalendar({ events: [e] });
// Remove event from the calendar
$("#calendar").fullCalendar('removeEvents', 1);
// Try re-adding event, doesn't work!
$("#calendar").fullCalendar('renderEvent', e);
Thanks!
Why can't a removed event be re-added to FullCalendar if it was part of
the original events array at calendar creation?
This works (http://jsfiddle.net/fTu98/1/):
// A simple event object
e = {id: 1, title: 'a', start: Date.now()/1000 };
// Create calendar with no events
$("#calendar").fullCalendar({ events: [] });
// Add event to calendar
$("#calendar").fullCalendar('renderEvent', e);

$("#calendar").fullCalendar('removeEvents', 1);
// Re-add event

Project euler benchmark
Project euler benchmark
I recently started solving Project euler for fun. and I thought it would
be awesome to have benchmarks shared out here. No solution algorithms,
just times and results for comparison (so anyone can still solving
problems on their own, but also check if is there faster solution).
I know its not really a question but still i think it could help. If you
can add your results (if they are better than others already here) in
similar format as mine.
so here are my so far (i will add missing ones when finished):

Xcode Autolayout - Constraint equal to another constraint
Xcode Autolayout - Constraint equal to another constraint
I am finally trying to adopt autolayout in IB and I am having trouble
setting the constraints for some objects. I basically want 5 views to be
equally distributed vertically throughout the superview. I have 3 buttons

WITHOUT resizing the height of anything. How can this be set up in IB?

Define web root dir - consant works on include but not redirect
Define web root dir - consant works on include but not redirect
I'm trying to create a constant which defines my web root dir, which I can
use for constructing paths for requires, header redirects, images, etc.
I need the constant to work when used in files in the root folder and sub
folders. I know I could easily hard code the paths with ../ etc, but the
main reason I'm trying to get this to work (apart from clean code) is so I
can re-use the code on various sites on different servers, where the path
may vary.
my dir structure
/
index.php
/library
libSetPathRoot.php
Document Root
echo $_SERVER["DOCUMENT_ROOT"];
Returns: /home/james/web/sites/
The "sites" dir contains various document roots defined in sites-available
(so I can work on different scripts).
File contents
/index.php
require_once('library/libSetPathRoot.php'); //works fine.. of course
/library/libSetPathRoot.php
define("PATHROOT", realpath(__DIR__ .'/..').'/');
The above returns my root correctly:
echo PATHROOT;// /home/james/web/sites/site3/
I've tried the following and various other code to define a root path.
These, and others, didn't work for redirect(), include(), nothing at all:
define ('PATHROOT', getenv("DOCUMENT_ROOT"));
define ('PATHROOT', basename(dirname((__DIR__))));
echo PATHROOT;
Everything else seemed to return "site3" only.
The working define works for include() and require() regardless of where
in the dir structure it is placed. ie if in file in sub dir to root
calling root or other sub dir to root, in a file in root, included file
etc.
But I just cannot get this working for header() redirect. Again,
regardless of where I use it - root scripts, sub folder scripts, included
scripts. Maybe I need another approach, but have read numerous options and
tried them extensively (half a day spent).
Why is my define working for includes but not header redirect, and how can
I make it work on all? Or do I have to use two methods, one for include
and one for redirects?

Supposing i have a dictionary that I have created using defaultdict like
this one(many hundred points long):
L [(32.992, 22.861, 29.486, 'TYR'), (32.613, 26.653, 29.569, 'VAL'),

H [(-0.511, 19.577, 27.422, 'GLU'), (2.336, 18.416, 29.649, 'VAL'), (2.65,
19.35, 33.322, 'GLN')
I then want to loop over every value in each key and check the distance
from that value to every other residue under the other keys. I know how to
check the distance using a simple formula, but I am having problems
getting the loop to work properly. Ideally it would check each point in L
against each point in A and H and then move on to checking each_value in A
against L and H etc...
I have tried simple comprehensions but I always get only one chain to
check one other chain before it finishes. Any help is appreciated.

How can I use a db through different Activities in android?
How can I use a db through different Activities in android?
I created an SQLite database in my Android project to store information
about homes using SqliteOpenHelper.I have two Activities.One is a list
activity containing a list of all homes, and one that is started by the
listActivity to add a new home. My question has to do with the usage of
the db. Which is better? Have an instance of the db in both activities? Or
have a static instance of the db in only one activity and use it in every
other activity that need acces to it? What is the better way to use a db
through different Activities?
public class HomeDatabaseHandler extends SQLiteOpenHelper{
//Database Version
private static final int DATABASE_VERSION = 1;
//Database name static value
private static final String DATABASE_NAME = "homeManager";
//Table name
private static final String HOMES_TABLE = "homes";
//more code here for adding creating etc...
}
public class MainActivity extends ListActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Here is my db for populating listView
HomeDatabaseHandler db = new HomeDatabaseHandler(this);
}
//in Activity to add home
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_add_done:
//more code here to get values from views
//create new db to add values
HomeDatabaseHandler db = new HomeDatabaseHandler(this);
//method to add home
db.addHome
}
}
This is how it looks right now, creating to instances of the Handler and
adding. So what do you think?I feel this is not the best way...

Test classes with common behavior
Test classes with common behavior
I have to write some integration test classes in the Hybris Commerce Suite
and most of them share a common behavior to set up the system (Site,
Store, Catalog, Country, ...) or to perform some common action like create
a customer.
I created an abstract class that perform all the initialization with
constant values in the @Before method and with some common methods like
createDefaultCustomer().
All my test classes inherit from this class.
The constant values are separated in different constant classes like
abstract class AbstractTest {
protected static final class USER_CONSTANTS {
};
protected static final class CATALOG_CONSTANTS {
};
protected UserModel createDefaultUser() {
}
}
Now, in order to test, in my subclasses i can do
createDefaultUser();
UserData userData = userFacade.getUserById(USER_CONSTANTS.ID);
assertEquals(USER_CONSTANTS.ID, testUser.getId());
If I don't do this there is a lot of duplication in test classes.
My doubt is whether this is acceptable because the abstract class tends to
be long and rich of methods or I need to change the design. I would to
avoid the creation of separate classes for each group of constants.

IPad use as a monitor with an Hdmi feed into it
am trying to find out if a live HDMI signal can be fed into an iPad , so
that the iPad is becoming a monitor for that live HDMI Video signal feed.
wifi is not an option , because of the delay.
i called apple, and have virtually had 2 contradictory answers, one senior
advisor asked the tech dept and came back and said its not possible, no
incoming signal is possible, only outgoing.
then the second call they said it would work, hence the data of an SD
memory card can be imported , otherwise such imports would not be possible
neither.
i would like to find out with a blue prints reasoning what the story is now.
any technical proof what the case is would be greatly appreciated.

I am using "false" tag to show Menu items in the given text style instead

Wordpress ACF: Image field, change image on mouse over
Wordpress ACF: Image field, change image on mouse over
I have a flexible content field containing a name, a link to a personal
page and 2 image fields (both returning object id): the original image and
a "mouse-over" image.
I want to display these fields on a page, so i added the following code
(between a while-statement, but that messes up the code:
<?php if(get_row_layout() == "medewerker"): // layout: Content ?>
<div class="medewerker_blok">
<div class="med_naam">
<?php the_sub_field("med_naam"); ?>
</div>
<a href="<?php the_sub_field('medewerkers_pagina'); ?>" >
<div class="med_foto">
<?php $image =
wp_get_attachment_image_src(get_sub_field('med_foto'),
'medium'); ?>
<?php $thumb =
wp_get_attachment_image_src(get_sub_field('med_foto'),
'thumbnail'); ?>
<img src="<?php echo $image[0]; ?>" alt="<?php
the_sub_field('med_naam');?>" rel="<?php echo $thumb[0];
?>" />
</div>
</a>
</div>
<div class="clear"></div>
<?php endif; ?>
This works fine: it shows the name field, the image. So far so good. But
now I would like an option where it replaces this image with the second
image field when you hover over the picture.
I cant get it working, must be missing something.
Please note, it is a flexible field, so the mouseover shouldn't trigger al
the other repeated blocks.
I hope someone can help me with this!
Cheers,
Bram

Convert string formatted as yyyymmddhhnn to datetime
Convert string formatted as yyyymmddhhnn to datetime
I have a table in an SQL Server database with a date field in it,
presented as varchar in yyyymmddhhnn format (where nn is minutes). For
example, 200012011200 would be 01 Dec 2000 12:00. I need to convert this
to a datetime value, but none of the convert codes seems to cover it. It's
closest to ISO format yyyymmdd but that doesn't include the time part, so
calling convert(datetime, MyDateField, 112) fails.
The time part is important, so I can't just strip it off. How can I
convert this to datetime?

DictionaryBase - Get specific item
DictionaryBase - Get specific item
I have a Class that inherits DictionaryBase. The Dictionary is <Object,
DataSources>.
Given all Key, Value pairs, there should only be one CustomClass that has
a property of isPrimary. I want to create a property that returns the
Primary object and I can't seem to find the best way to approach this:
Public Class DataSources
Inherits DictionaryBase
Friend Sub New()
MyBase.New()
End Sub
Public Sub Add(ByVal Key As Object,
ByVal NewDataSource As DataSource)
Dictionary.Add(Key, NewDataSource)
End Sub
Default Public Property Item(ByVal Key As Object) As DataSource
Get
Return CType(Dictionary.Item(Key), DataSource)
End Get
Set(ByVal Value As DataSource)
Dictionary.Item(Key) = Value
End Set
End Property
Public Shadows Function GetEnumerator() As IEnumerator
Return Dictionary.Values.GetEnumerator
End Function
Public Sub Remove(ByVal Key As Object)
Dictionary.Remove(Key)
End Sub
End Class
I'd like to do two things:
1) Prevent 2 isPrimaries. Search the dictionary and throw an error if
isPrimary already exists and we try to insert another.
2) Get the Primary Value for the Dictionary.
I cant' seem to find good examples using DictionaryBase...

Django - logging each view's action
Django - logging each view's action
I'm thinking of creating a log system for my django web application. The
web application is quite comprehensive in its use (covers all aspects of a
business's processes) so I'd like to track every event that happens.
Specifically, I'd like to log every view that runs and not just the "main"
ones and, potentially, log what is happening within the view as its
executed.
While I'm in the "idea" stage of the logging system, I've quickly hit a
few questions that leave me unsure how to proceed. Here are the main
questions I have:
I'm thinking of logging all of the events in the same MySQL database that
the main web app holds its data. The concern I have is bloating the MySQL
database into a massive DB. Also, if the DB crashes or is destroyed
somehow (yes I have backups) I'll loose my log too which blows away any
ability to track down the problem. Do I use a seperate DB or just go with
text files?
How granular do I go? Initially I was thinking of simply logging things
like, "Date - In view myView". However, as I'm thinking about it, it would
be nice to log all the stuff that happens within the view. Doing this
could make the log massive! and would also make my code ugly with so many
log entry lines mixed into the code. This kind of detail:
Date - entered view myView
Date - in view myView, retrieved object myObject from the DB
Date - in view myView, setting myObject field myField to myNewValue
Date - leaving myView
Those are my main thoughts at this point. Any advice on this front?
Thanks

I want to eval concatenated symbols in ruby
I want to eval concatenated symbols in ruby
I'm trying to find a way to concatenate module and class names to give me
more info. In cases where I can Enumerate things like constants, I want to
tack on to them and eval them somewhat. I've seen something like this
before but just don't remember where.
Errno.constants.sort.each do |name|
string = '#{Errno}::#{name}::#{Errno}'
puts eval("\"" + string + "\"")
end
How might I get something like this to work so that I don't have to
individually list the full name such as
puts Errno::E2BIG::Errno

But as result i get:

What do I miss?

PHP Time and JavaScript Time
PHP Time and JavaScript Time
I have a bit of a situation here. I have a simple task which is to allow a
user to do something on a web app in timed intervals. Say, I did the
action now, I should only be able to perform the action again after 10
min.
Server time and client time are in different timezones. I keep server time
in my DB. I would appreciate help in converting server time to the time
zone of the client machine so that I can do the check in the front end
instead of another extra trip to the server.

How to get the value of a Controller variable in rails console
How to get the value of a Controller variable in rails console
I set a variable inside a Controller and I'm trying to just do something
as simple as read that variable in the rails console.
I thought about just doing @test in the console which is the name of the
variable. but it shows as >null. When I do puts under where I set the
variable it traces out the correct value in my terminal window.
Any ideas what I need to do to get to this variable via the console.
I tried putting the name of the controller first and then .variable but
that threw an error
I can see what's inside my models by just using the model name and some
attributes like .first and .last

Create CSS Hover Image in Wordpress
Create CSS Hover Image in Wordpress
I have a site here...
When you look at this page, you'll see an image of a comment bubble...
Here's the CSS attached to that comment bubble...
#content .postmetadata .comments {
background-image:url(images/comment.png);
background-repeat:no-repeat;
position:absolute;
bottom:8px;
height:25px;
*bottom:18px;
margin-left:8px;
}
What I'm trying to do is, by default have the image that you see there...
(it's black with about 50% opacity).
When you hover over it, the image turns red, but keeps the background
transparent, so it's only the bubble that changes color.
I have the red image ready, or is that something I can do with CSS?
Does that make sense?

alternative to std::advance which doesn't modify the input
Cannot manage to find it, hope somebody can help. There is a function in
the std library which gets called upon an iterator and an unsigned number,
which returns the iterator pointing to the object to which the input

Which function am I referring to? I'm sure it exists!

for(i = 1; i <= sizeof(vdates); i = i+1)
daily_file = selectifr([bid,ask], dates .== vdates[i]);
if empty continue
save daily_file contract_name + "_" + sprint(vdates[i]) ;
How do I translate this program into Matlab?

Any ideas how i can find my div element based on ID? And how to update it
with new text? (the div i want to update is the inner one with msg inside
Im trying to loop over a JTextPane and find a element which has a certain
ID. I then want to be able to update the element with new text.
What i got so far:
Element root = ta.getDocument().getDefaultRootElement();
BranchElement current = (BranchElement) root.getElement(0);
if (current != null) {
Enumeration children = current.children();
while (children.hasMoreElements()) {
Element child = (Element) children.nextElement();
AttributeSet attrSet = child.getAttributes();
System.out.println(child.getAttributes());
//ImageIcon icon = (ImageIcon)
StyleConstants.getIcon(attrSet);
//System.err.println(icon.getDescription());
}
}
This is how my insert looks like:
try {
kit.insertHTML(doc, doc.getLength(), "<div style=\"padding-top:10px;
padding-bottom:10px;\" id=\"X\">" + "<div>" + from + " at
" + tid + ":</div>" + "<div style=\"padding-top:4px;" +
align + "\">" + msg + "</div>" + "</div>", 0, 0, null);
} catch (BadLocationException ex) {
Logger.getLogger(Client.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(Client.class.getName()).log(Level.SEVERE, null, ex);
}

Rails create and new creating different objects
Rails create and new creating different objects
I have a model Project and a model Test. Project has many Tests.
My tests_controller has:
def new
@project = Project.find(params[:project_id])
@test = @project.tests.new
end
def create
@project = Project.find(params[:project_id])
@test = @project.tests.create(test_params)
end
So in my new.html.erb, I present a form, and when submit is pressed,
create is called. I'm confused however because what is apparently
happening is that I am creating one test in new and a whole different test
in create. What is the correct paradigm for what I am trying to achieve?

windows 7 clean and pure registry file - where to obtain?
where can I obtain clean and pure windows 7 registry file?
by pure and clean I mean registry file that does not contain any records
from an other software than windows
...obviously I do not want to reinstall windows ...my goal is to compare
the registry in the current state with the original clean registry...in
order to identify all changes done to it since installation
Anybody?

Radgrid get cell value when in edit mode
Radgrid get cell value when in edit mode
I have a radgrid and a textbox where I would like to show the value of a
column when the record is in edit mode. The value I would like to get is
contained in a readonly column and it is listed in DataKeyNames, it is
basically the transaction id given by the SQL database when the item is
created.
<MasterTableView CommandItemDisplay="TopAndBottom"
DataSourceID="SqlDataSource1" AutoGenerateColumns="False"
DataKeyNames="TransazioneID" AllowFilteringByColumn="True">
I cannot get it out.
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item is GridEditableItem && e.Item.IsInEditMode)
{
GridEditableItem item = e.Item as GridEditableItem;
string str = item["TransazioneID"].Text;
TextBox1.Text = str;
The code doesn't give me errors but shows nothing. How can I get the value
of "TransactionID" for the record in edit mode?

Role of placeholder in Boost::bind in the following example
Role of placeholder in Boost::bind in the following example
There are numerous example on SO regarding the use of placeholders however
I am still a little bit confused and would appreciate it if someone could
explain the difference between the following two statements
void SomeMethod(int a)
{
std::cout << "Parameter pass " << a << "\n";
}
Statement 1 : boost::bind(&SomeMethod,_1)(12);
Statement 2 : boost::bind(&SomeMethod,12)();
I believe I understand statement 1 which is chaining. The output of
boost::bind(&SomeMethod,_1) gets to have a parameter of 12 attached to it.
However I have difficulty understanding whats happening in statement 2. If
a parameter could be passed directly using boost::bind (as in statement 2)
then why the need of a placeholder ?

Paypal Sandbox IPN no Repsonse
Paypal Sandbox IPN no Repsonse
I am using Zend Framework 2 as my listener for a Paypal payment. My
listener is triggered when the payment is made in the sandbox environment,
but when i generate the request to reply to Paypal in order to get a
VERIFIED or INVALID respone i do not get a response. There is nothing
coming up in the web server logs, no errors and no exception is thrown.
Have tried both the dispatch and Send methods
Is there any way i can see if the request is sent to Paypal sandbox?
Anywhere in the sandbox i can see this? Or is there anyway i can see the
response come back. Am using Amazon WS but i dont think its getting
blocked as the listener is initially triggered.
Many thanks
Code for IPN listenter is below: $request = $this->getRequest();
// Follow Paypal IPN protocol
// First send back to PayPal received request
$request = new Request();
$request->setMethod(Request::METHOD_POST);
$client = new Client();
$client->setRequest($request);
$client->setUri('https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_notify-validate');
$postArray = $request->getPost()->getArrayCopy();
$client->setParameterPost($postArray);
$requestHeaders = $client->getRequest()->getHeaders();
try {
$response = $client->send();
//$response = $client->dispatch($request);
} catch (Exception $e) {
$logger->info("Exception:");
$logger->info($e->getMessage());
